Moon for August
4 full, 5 apogee, 12 last quarter, 19 new, 19 perigee, 25 first quarter
The apogee of the moon is on 5 August (252,444 miles far), while the perigee (221,927 miles near) is on 19 August.
The Perseid meteor shower peaks 12 and 13 August under the last quarter moon. Best viewing to see its spectacular fireballs is a
couple hours before dawn. The Kappa Cygnid shower with its slower meteors with yellowish tails peaks 17 August with the new
moon.

Donald, I am afraid I would have to post your Earth and Sun Digest line by line with commands in,<> brackets to have it come out the way you send it to me, but it is still worthwhile having it. I had no trouble following the tables once I read the top line. Thanks! (I was not ignoring you, I simply could not post this till now.) Now I await the next one or go snitch it from world Seismology.

SPECIAL REPORTS (2)
The Ash of Tungurahua
The Earth and Sun Digest has documented the weekly high eruptions of Mount Tungurahua in Ecuador since at least April.
What happens to this ash? The Global Volcanism Program from the Smithsonian archives answers such questions in a
program no longer funded, called "Ask a Volcanologist". Here is the answer to "How high can explosive eruptions go and
how far can the ash be spread?", with pictures and a comment on the effect of ash on global cooling:
http://volcano.und.nodak.edu/vwdocs/frequent_que stions/top_101/Eruption/Eruption6.html
The archive is at: http://volcano.und.nodak.edu/vwdocs/frequent_questions/top _101/Eruption.html
This report from Tuesday is an example of the distribution of ash after an eruption of Tungurahua to 26,000 feet:
http://www.nmnh.si.edu/gvp/gvn/aviation/sab00110.htm
The prevailing winds at the Equator are westerly, so ash from Ecuador and Indonesia goes west over the El Nino eastern
Pacific area, and can affect India, eastern Africa and the Middle East.

Moon for August
4 full, 5 apogee, 12 last quarter, 19 new, 19 perigee, 25 first quarter
The perigee of the moon (221,927 miles near) is on 19 August.
Today on www.SpaceWeather.com is this report:
"RADIATION STORM: The flux of high-energy protons around our planet soared
to 1000 times normal at ~0300 UT on August 16th. The ongoing S2-class solar
radiation storm is unusual because it was not triggered by a major flare on
the Earth-facing side of the Sun. Instead, it appears to be the result of a
backside explosion detected by SOHO coronagraphs on August 15th."
The Kappa Cygnid meteor shower has slower meteors with yellowish tails than
the Perseid. It peaks 17 August. The New Moon helps visibility. See
www.spaceweather.com
Recent Volcanic Ash Eruptions:

Addendum from Donald Boon:
All,
In reviewing the chart for the monthly 6M or greater quakes in the world in
preparation for today's Digest, I noted some incorrect number from duplicate
counting at the end of September.
The full count for September 2001 is thus 10.
In October 2001 we have experienced 9 quakes 6M and greater, of which two
were seven or greater.
The September, October and Yr. total lines for Oct. 25 should read:
YEAR: 93 94 95 96 97 98 99 00 01

SOLAR SPOT: Sunspot 9682, in the center of the sun, now covers an area equal
to nearly seven planet Earths. It has a twisted "delta-class" magnetic field
that poses a threat for X-class solar flares. See www.spaceweather.com , a
click-date reference, and SUN section.
Simple ways to view these sunspots without a telescope are described at:
http://spaceweather.com/sunspots/doityourself.html
Do not look at the sun directly. That causes blindness.
Volcanic Gases and Drought: The sulfur dioxide and other gases produced by
volcanoes contribute to drought. The Recent Volcanic Eruptions section and
the FIVE Rule will add an emphasis on gases to that on ash. See also SPECIAL
REPORT.

With thanks and Happy New Year to Donald Boon for his continued Good Works:

All,
During this transition for our group interested in quakes and volcanoes
please note that I will only be posting the brief form of the Earth and Sun
Digest here on Yahoo! The full version can be viewed at www.bbmessages.com
under Planet Earth/Seismology, which to date is basically an archive.
I do not know what is happening to Marcia, but here publicly I state that
Marcia has always had my permission to publish the Earth and Sun Digest on
her conferences. She has been an invaluable aide to me at acquiring needed
information for the Digest when it was not available via the usual channels.
I wish her, and indeed all of you well, as we try to help prevent casualties
from these massive "acts of God".
If there is any reason for the strange happenings on Yahoo!, I suggest that
it is because there is a competing group or two who claim to be more
scientific.
Here is the current brief Digest:

None of these apparently caused much injury or damage, but more could come in the next few days because of the positions of the moon and sun, as noted above.
This digest is focused using "The FIVE Rule":
FIVE quakes of 5.x magnitude in FIVE Days
can cause a volcano to erupt ash and gas FIVE miles to the jet streams, where at mid-latitudes it can circle the globe in FIVE days.
Questions and comments are welcomed.

SPECIAL REPORT
Normal Seismic Activity During 2001, But Heavy Toll in Human Losses
The year 2001 was a typical year based on historical seismic activity,
producing 65 significant earthquakes worldwide and causing 21,436 fatalities
according to the U.S. Geological Survey (USGS). Significant earthquakes are
those of magnitude 6.5 or greater or those that cause fatalities, injuries
or substantial damage. During a typical year, 18 major temblors (magnitude
7.0 to 7.9) and one great earthquake (8.0 or higher) occur worldwide.
Complete article can be found at
http://www.usgs.gov/public/press/public_affairs/press_releases/pr1543m.html
(thanks to Bonnie Schafer for finding this)
This digest is focused using "The FIVE Rule":
FIVE quakes of 5.x magnitude in FIVE Days
can cause a volcano to erupt ash and gas FIVE miles to the jet streams,
where at mid-latitudes it can circle the globe in FIVE days.
Questions and comments are welcomed.

SPECIAL REPORT
Dead Sea Still Sinking
Both of the biblical seas have been greatly affected by the Middle East
drought. The Dead Sea water level has dropped 2.5 inches a year since 1992.
See http://www.cnn.com/2002/WORLD/meast/01/14/deadsea.sinking.ap/index.html
Despite the recent rains, the Sea of Galilee level is under its red line.
The fall is compared to Los Angeles, which sees a yearly 4 inch variation up
or down, depending on conditions. The Dead Sea, however, is less seismically
active. See map and list of the most recent quakes around Israel at:
http://www.gii.co.il/html/seis/seis_fs.html
PREDICTION CONTEST: Sandi's List
Sandi Harrington noted last summer that there is increased susceptibility to
big quakes with coincidence of the full moon and the perigees of the moon.
Such a coupling occurs with close perigees through March and January's first
two weeks brought more than December's number of 6M quakes. While the number
may fall as quake susceptibility diminishes, now is the chance for
predictors. Through 10 April, 2002, under SPECIAL REPORTS will appear
SANDI'S LIST, a chart of earthquake predictions by members from Yahoo!,
Prodigy and BBMessages.com, after they are first posted on at least one
board. The predicting note must include the information in the RULES posted
above and the predictor must be identified by signature in the note. Posting
is at the sole discretion of the Digest. Predictions will be removed from
the list after the date predicted, but accurate predictions will be noted in
the Honor Roll.
The allowed margin of error for published epicenter is one degree of
latitude and longitude, for time is one week from a specific date (which is
regarded as mid-week), and quake magnitude down to 4.5M on public USGS
charts. A=in prediction, B=within limits; ABB predictions are honorable.
Note: Since prolonged dwelling on the gift of earthquake sensitivity can
cause major illness, any liability for predictions belongs solely to the
contributors. Since earthquake sensitivity is real, however, and society
needs reliable methods of predicting major quakes, the Digest is promoting
this exercise to help identify people who truly have the gift, as well as to
help save lives. A personal journal can assist anyone trying, and is a hedge
against depressing symptoms. Only predictions will be shown here.
CREDITS as of this issue will be given to members of Yahoo!, BBMessages.com
and Prodigy for alerts to articles of interest used in Digest. Selection is
solely the right of the editor.
This week also I want to publicly thank Prodigy Special Contributors Ray
Gallagher and Allison Rhoden for training me in use of seismic data, to
Diane Pope for starting the monthly 6M quake chart on Prodigy, and Marcia
for clueing me on volcanic gases.
Questions and comments are welcomed.
Donald J. Boon, editor, pijskk24a@prodigy.net
*An aside from Marcia. Donald's earthquake contest is one I will not enter. He dedicated it to Sandi, and she "suddenly" formulated her theory when John (and my son for that matter) had done it when she was still too young to have studied the science and have worked in the field. My speculation and studied predictions will remain in Geo with Rob, John and other professionals I trust.*

Do not worry Marcia. A list without proof is nothing particularly when they are deleting pointless predictions. This is the way that led many scientists around the world to allege that does not exist any relationship between earthquakes and tidal forces. Poor statistics again.
We prove every day in Geo what connection between earthquakes and tidal forces exists. We have to delete nothing. OUR PREDICTIONS ARE TOTALLY CORRECT. They need proves by measurements and scientific methodology. I will say that that list is an amateur attempt.

(All data are preliminary, more tables at www.bbmessages.com )
Earthquakes of 5.0 to 5.9 mag thru Wednesday--16; one quake of 6M or
greater: 6.0M SOUTH SANDWICH ISLANDS REGION
California earthquakes in past week--208
Volcanic Ash over 5 mi (8 km)--Ecuador
Sunspot No. High--229 on 8 February
Geomagnetic A-Index High--16 on 6 February
Moon for February
4 last quarter, 12 new, 14 apogee, 20 first quarter, 27 full, 27 perigee
The apogee of the moon is 14 February (252,502 miles far), while the next
perigee is 27 Febrary (221,722 miles near)
The moon's longest runs start today. The time for the run is basically the
same, but the distance the moon moves from far to-and-from near points is
maximal, meaning this is also the fastest run. Adapted from last week's
table here are the distances (apogee=A, perigee=P):
Jan 30 P 27818 miles to
Feb 14 A 29678 miles to
Feb 27 P 29884 miles to
Mar 14 A 29816 miles to
Mar 28 P 29638 miles to
Apr 10 A
The February perigee is the closest near point of the year, and with the
full moon provides the maximal tidal stress on the earth. The moon is on the
ellipse and even occults Jupiter on 23 February. The Spring Equinox is March
20. The effect on the earth (earthquakes and volcanic eruptions) also
depends on local geological susceptibility.

WHERE ARE THE BIG EARTHQUAKES?
(from Yahoo! Pinpoint, 2/26/02, updated)
The Earth and Sun Digest Quake Prediction Contest was based on the
idea that the full moon and the nearest perigee of the moon should
increase the tidal effect on the earth for both the ocean and the
mantle, and generate big earthquakes.
So far just one quake has occurred at one day post perigee. Why the
decrease?
One explanation might be that February is not normally a month for big
quakes: See above monthly totals.
Another possibility is that big quakes are focused into a smaller
time frame.
January's first perigee was Jan. 2. Here was the focus of quakes:
02/01/01 10:39:00 6.0M PACIFIC-ANTARCTIC RIDGE
02/01/01 11:29:22 6.3M MINDANAO, PHILIPPINES
02/01/02 17:22:49 7.2M VANUATU ISLANDS
02/01/03 07:05:27 6.1M HINDU KUSH REGION, AFGHANISTAN
02/01/03 10:17:39 6.4M VANUATU ISLANDS
There were two 6M quakes in December 2001, on the 23 and 27 December.
So, has susceptibility been exhausted?
The second perigee was on 30 January . Here were the quakes:
02/01/28 13:50:28 6.1M KURIL ISLANDS
02/01/28 15:09:55 6.0M TONGA ISLANDS
02/02/01 21:55:20 6.0M PRIMORYE, RUSSIA
02/02/03 07:11:29 6.2M AFYON PROVINCE, TURKEY
02/02/03 09:26:43 6.0M AFYON PROVINCE, TURKEY
While there were no 6M quakes the week prior to the perigee on 27 Feb.,
there were 5M quakes, and the number of quakes in the past week in
California and Nevada soared to 400, with aftershocks.
Questions and comments are welcomed.

Response 43 of 85: John Tsatsaragos (tsatsvol) * Sun, Mar 24, 2002 (07:10) * 10 lines
Apropos of the response 243 in topic 50 from Cheryl, I will try to give you some astronomical elements for the equinox. You must give some additional attention because we will use Right Ascension on maps of night sky.
We have Equinox two times per year. It is either of the two points at which the celestial equator intersects the ecliptic, and also the times when the Sun passes through either of these points. The Sun passes from south to north at the northern vernal (spring) equinox and from north to south at the northern autumnal equinox. The approximate dates are 21 March and 23 September.
The position of the northern vernal equinox is also traditionally known as The first point of Aries. However, the effects of precession have gradually moved the point so that it now actually lies in the adjacent constellation of Pisces.
First point of Aries is also the zero point of Right Ascension (RA) measurements. RA is one of the coordinates used to define position on the celestial sphere in the equatorial coordinates system. It is the equivalent of longitude on the Earth but is measured in hours, minutes and seconds of time eastwards from that zero point. One hour of right ascension is euivalent to 15 degrees of arc; it is the angle through which the celestial sphere appears to turn in one-hour of sideral time, as the Earth rotates.

You are amazing, John! I was just printing out a sky chart with the hope of seeing the comet tonight. Of course I have declanation and right ascention on the maps and I use it automatically from setting telescopes manually for so many years. I have gotten so I can estimate it pretty closely when I am outside. Degrees are also good to know.
Procession of the Equinoxes - I think that deserves graphics and perhaps more text. Everything, it will be discovered rather quickly, is relative.

Response 46 of 85: Moon Dreams (Moon) * Thu, Mar 28, 2002 (16:18) * 46 lines
The perigee of the moon is today, 28 March (221,836 miles near).
For those interested in the Moon as I am, here is some history.
Full Moon names date back to Native Americans, of what is now the northern and eastern United States. The tribes kept track of the seasons by giving distinctive names to each recurring full Moon. Their names were applied to the entire month in which each occurred. There was some variation in the Moon names, but in general the same ones were current throughout the Algonquin tribes from New England to Lake Superior. European settlers followed that custom and created some of their own names. Since the lunar month is only 29 days long on the average, the full Moon dates shift from year to year.
Here is a listing of the full Moon names:
Full Wolf Moon Amid the cold and deep snows of midwinter, the wolf packs howled hungrily outside Indian villages. Thus, the name for January¹s full Moon. Sometimes it was also referred to as the Old Moon, or the Moon After Yule. Some called it the Full Snow Moon, but most tribes applied that name to the next Moon.
Full Snow Moon Since the heaviest snow usually falls during this month, native tribes of the north and east most often called February¹s full Moon the Full Snow Moon. Some tribes also referred to this Moon as the Full Hunger Moon, since harsh weather conditions in their areas made hunting very difficult.
Full Worm Moon As the temperature begins to warm and the ground begins to thaw, earthworm casts appear, heralding the return of the robins. The more northern tribes knew this Moon as the Full Crow Moon, when the cawing of crows signaled the end of winter; or the Full Crust Moon, because the snow cover becomes crusted from thawing by day and freezing at night. The Full Sap Moon, marking the time of tapping maple trees, is another variation. To the settlers, it was also known as the Lenten Moon, and was considered to be the last full Moon of winter.
Full Pink Moon This name came from the herb moss pink, or wild ground phlox, which is one of the earliest widespread flowers of the spring. Other names for this month¹s celestial body include the Full Sprouting Grass Moon, the Egg Moon, and—among coastal tribes—the Full Fish Moon, because this was the time that the shad swam upstream to spawn.
Full Flower Moon In most areas, flowers are abundant everywhere during this time. Thus, the name of this Moon. Other names include the Full Corn Planting Moon, or the Milk Moon.
Full Strawberry Moon This name was universal to every Algonquin tribe. However, in Europe they called it the Rose Moon.
The Full Buck Moon July is normally the month when the new antlers of buck deer push out of their foreheads in coatings of velvety fur. It was also often called the Full Thunder Moon, for the reason that thunderstorms are most frequent during this time. Another name for this month¹s Moon was the Full Hay Moon.
Full Sturgeon Moon The fishing tribes are given credit for the naming of this Moon, since sturgeon, a large fish of the Great Lakes and other major bodies of water, were most readily caught during this month. A few tribes knew it as the Full Red Moon because, as the Moon rises, it appears reddish through any sultry haze. It was also called the Green Corn Moon or Grain Moon.
Full Fruit or Barley Moon The names Fruit and Barley were reserved only for those years when the Harvest Moon is very late in September,
Full Harvest Moon This is the full Moon that occurs closest to the autumn equinox. In two years out of three, the Harvest Moon comes in September, but in some years it occurs in October. At the peak of harvest, farmers can work late into the night by the light of this Moon. Usually the full Moon rises an average of 50 minutes later each night, but for the few nights around the Harvest Moon, the Moon seems to rise at nearly the same time each night: just 25 to 30 minutes later across the U.S., and only 10 to 20 minutes later for much of Canada and Europe. Corn, pumpkins, squash, beans, and wild rice—the chief Indian staples—are now ready for gathering.
Full Hunter¹s Moon With the leaves falling and the deer fattened, it is time to hunt. Since the fields have been reaped, hunters can easily see fox and the animals which have come out to glean.
Full Beaver Moon This was the time to set beaver traps before the swamps froze, to ensure a supply of warm winter furs. Another interpretation suggests that the name Full Beaver Moon comes from the fact that the beavers are now actively preparing for winter. It is sometimes also referred to as the Frosty Moon.
The Full Cold Moon; or the Full Long Nights Moon During this month the winter cold fastens its grip, and nights are at their longest and darkest. It is also sometimes called the Moon before Yule. The term Long Night Moon is a doubly appropriate name because the midwinter night is indeed long, and because the Moon is above the horizon for a long time. The midwinter full Moon has a high trajectory across the sky because it is opposite a low Sun.
Blue Moon For more than half a century, whenever two full Moons appeared in a single month (which happens on average every 3 1/2 years), the second has been christened a ³Blue Moon.² In our lexicon, we describe an unusual event as happening ³Once in a Blue Moon.² This expression was first noted back in 1821 and refers to occurrences that are uncommon, though not truly rare.
On past occasions, usually after vast forest fires or major volcanic eruptions, the Moon has reportedly taken on a bluish or lavender hue. Soot and ash particles, propelled high into the Earth¹s atmosphere, can sometimes make the Moon appear bluish.
Why ³Blue² Moon? For the longest time nobody knew exactly why the second full Moon of a calendar month was designated as a Blue Moon. One explanation connects it with the word ³belewe² from the Old English, meaning, ³to betray.² Perhaps, then, the Moon was ³belewe² because it betrayed the usual perception of one full Moon per month. However, in the March 1999 issue of Sky & Telescope magazine, author Phillip Hiscock revealed one somewhat confusing origin of this term. It seems that the modern custom of naming the second full Moon of a month ³blue,² came from an article published in the March 1946 Sky & Telescope magazine. The article was ³Once in a Blue Moon,² written by James Hugh Pruett. In this article, Pruett interpreted what he read in a publication known as the Maine Farmers¹ Almanac (no relation to this Farmers¹ Almanac, published in Lewiston, Maine), and declared that a second full Moon in a calendar month is a ³Blue Moon.²
However, after reviewing the Maine Farmer¹s Almanac, Hiscock found that during the editorship of Henry Porter Trefethen (1932 to 1957), the Maine Farmers¹ Almanac made occasional reference to a Blue Moon, but derived it from a completely different (and rather convoluted) seasonal rule. As simply as can be described, according to Trefethen¹s almanac, there are normally three full Moons for each season of the year. But when a particular season ends up containing four full Moons, then the third of that season is called a Blue Moon! To make matters more confusing, the beginning of the seasons listed in Trefethen¹s almanac were fixed. A fictitious or dynamical mean Sun produced four seasons of equal length with dates which differed slightly from more conventional calculations. So, basically the current use of ³Blue Moon² to mean the second full Moon in a month can be traced to a 55-year-old mistake in Sky & Telescope magazine.

That is so grea, Moon! Many thanks for such a comprehensive study of the moon. I really enjoy almanacs. They are full of "stuff" just like my mind is. Some of it irrelevant, but all fascinating.

17 April 2002
Details at: http://www.spacew.com/astroalert.html
ANOTHER EARTH-DIRECTED CME IS POISED TO STRIKE ON 19 APRIL
A major geomagnetic storm was observed on 17 April following the
early
arrival of an Earthward directed coronal mass ejection (CME) that was
launched from the Sun on 15 April. The disturbance has produced periods
of
strong auroral activity that has been visible across many middle latitude
regions. The present disturbed activity is expected to gradually subside
over the
next 12 hours prior to the arrival of the next incoming solar
disturbance.
Active sunspot region 9906 (the subject of recent AstroAlerts)
spawned a
long-duration solar flare earlier on 17 April that was associated with
another Earthward-directed coronal mass ejection. Forecasters expect this
disturbance to arrive sometime during the UTC day of 19 April.
Determining a
precise arrival time for this event has been complicated by the fact that
there were two coincident mass ejections in the same quadrant of the Sun
but
with differing trajectories (although from Earth they appeared to have
nearly
the same trajectory - an illusory effect caused by the timing and
geometry of
the events).
For those less familiar with UTC time, the impact of this disturbance
could occur anytime between roughly the early evening hours of 18 April
over
North America (EDT) to the late afternoon hours of 19 April (EDT). The
moon
will begin to become a factor in the evening for optimally observing
activity
until it sets.
The arrival of this disturbance is expected to herald a return of
minor
to major geomagnetic and auroral storm conditions. Observations of
auroral
activity ("northern lights") will be possible after the disturbance
impacts.
In addition, there is a chance this disturbance may produce slightly
stronger
levels of activity than the disturbance we are currently wading through.
The key to successfully observing auroral activity is knowing when to
look. For regularly updated information, refer to the aurora discussion
forum
available at: http://www.spacew.com/aurora/forum.html . Current forecast
information (updated several times a day during disturbed periods) is
also
available at the bottom of that page.
The middle latitude auroral activity watch was upgraded to a warning
earlier today following the arrival of the current disturbance. The
warning
will be extended through to the latter part of the UTC day of 20 April to
cover the anticipated arrival (and effects) of the next coronal mass
ejection.

SYNOPSIS...
A coronal mass ejection has been observed passing the ACE spacecraft at
08:03 UTC on 19 April. This disturbance is associated with high solar wind
velocities (greater than 600 km/sec) and contains moderately strong magnetic
fields. Although the magnetic fields associated with the shock front are not
particularly favorable for producing immediate auroral storm activity, there
is a good chance periods of moderate to strong auroral storm activity will
follow in the next 12 to 18 hours. Observers are encouraged to keep a close
eye on conditions. The disturbance is projected to impact the Earth near
08:41 UTC on 19 April (4:41 am EDT).
This warning will remain in effect until 19:00 UTC on 20 April. It will
then be updated or allowed to expire.

CANNIBAL CME'S IMPACT: the first interplanetary shock wave swept Earth
today, 23 May, and triggered an ongoing G3-class geomagnetic storm. The
shock wave was the leading edge of a coronal mass ejection that left the Sun
on 22 May. It was likely a "cannibal coronal mass ejection" -- a combination
of three rapid-fire CMEs. Cannibal CMEs are thought to produce prolonged
geomagnetic storms.
Check today's www.spaceweather.com for more, including the coronograph
showing the three.
A X-2 Class Solar Flare occurred on the surface visible to earth, but was on
the edge and not directed toward earth. Another from a larger group, equal
to five surface areas of the earth, is capable of a bigger X class flare and
is nearing the center of the visible solar area. Such a flare would be
directed toward us, if it occurred in the next few days. See more at

Hi friends
ATTENTION!
DO NOT SEE THE SUN DIRECTLY WITHOUT PROTECTION.
Eye Safety And Solar Eclipses
…However, observing the Sun can be dangerous if you do not take the proper precautions. The solar radiation that reaches the surface of Earth ranges from ultraviolet (UV) radiation at wavelengths longer than 290 nm to radio waves in the meter range. The tissues in the eye transmit a substantial part of the radiation between 380 and 1400 nm to the light-sensitive retina at the back of the eye. While environmental exposure to UV radiation is known to contribute to the accelerated aging of the outer layers of the eye and the development of cataracts, the concern over improper viewing of the Sun during an eclipse is for the development of "eclipse blindness" or retinal burns….

Mahalo, John! *HUGS* for posting such complete instructions. When I watch such things I use pinhole projection and can share it with many people. Perhaps this time my eclipse jinx will not continue and I might see it. So as not to offend the gods who determing weather, I will say nothing further, but I really do want to see te 67% totality we are supposed to have in central California.

I can say that this eclipse is yours Marcia. Nature has this gift waiting for you there. See carefully the above response 55. See especially the coordinates on the top of the graph. It is centered in your recent place. See also the time that is changing in each phase. I hope that is successful.
So, you will see something like that. Perhaps you will feel some strange emotions during the eclipse. Usually it changes the wind intensity and its direction temporarily. Temperature also reduces temporarily. The eclipse will open something like a big hole mainly in the lower layers of the ionosphere too. It has an interesting effect to communications by radio waves. Earth’s electric field is changed locally too. Enjoy it and make a description for our friends later.

John, I am so unhappy! My network connection for yahoo worked all day yesterday and now it is not working again. I dispair of talking to you again. I see you are online, and that is a joy.
David is carefully researching the eclipse and he is determined that I will see this one. Yes, I will make notes and tell all about it. I missed a total sclipse over my island in Hawaii, then I missed the annular eclipse in California the following year. I would love to see this one. The others were due to the reluctance of others to find time to take me to a clear sky. And, this was not a good excuse since the "driver" in question did nothing but sit around the house all day anyway. For some people, my priorities and requests are only heeded when it is convenient, so I do not make them anymore. Here, we all want to see it.
Thank you for excellent data and graphics. It will be very useful. I am keeping my fingers crossed

The satellites last night were numerous and everything from rocket boosters to the ISS-Shuttle linked together. Despite the less that inky sky that I am used to in Hawaii, my son's palm computer had a satellit viewing program in it and as each one entered our sky a little alarm would sound and a graphic of the sky would let us watch its progress. By knowing what is up there already, it was easy to find the out of place stars which were quietly gliding across the night sky. Tonight we will try for tracking using the wedding present David and Iris gave one another - a 10 inche Meade reflector telescope. That is also run by a small computer and has the most amazing abilities. It makes my old refractor seem very poor by comparison.
Some of the satellites we saw (some quite dim and some as bright as a planet) various Cosmos satellites (Russian) Okean (Russian) SeaSat, Lacrosse, and ADEOS. Each has a number because so many of them are up there. The cosmos satellites we saw were Cosmos 1455, 1606, and 2237 (the latter we got to see the rocket that put it up there as well - quite a lot brighter.) To see how many satellites are really up there I suggest you use http://liftoff.msfc.nasa.gov/RealTime/JTrack/ If you have the power in your computer and the RAM necessary, pull up the graphic with ALL the satellites. It looks like we are encircled by a swarm of bees!

my kids and i watched the eclipse via two cardboard pieces. one had the pinhole (pencil hole) and the other had white paper taped to it. curious how it shows the sun through there. i had originally thought it would be a total eclipse but alas, it wasn't. this was the first time i had ever really watched it happen this way. we started losing the sun to the house behind us so we moved our station out of the yard. we attracted some attention and the kids who gathered wouldn't heed my warning about looking right at it. a co-worker saw it through camera film. i took pictures of each stage until the moon began it's descent (for us, the moon slid down from top to bottom). of course, i took pictures of it via the cardboard layout, not directly at the sun. will post them once they're developed!

Solar energy
Solar energy, any form of energy radiated by the sun, including light, radio waves, and X rays, although the term usually refers to the visible light of the sun. Green plants for the process of photosynthesis need solar energy. Photosynthesis is the ultimate source of all food. The energy in fossil fuels (e.g., coal and oil) and other organic fuels (e.g., wood) is derived from solar energy. Difficulties with these fuels have led to the invention of devices that directly convert solar energy into usable forms of energy, such as electricity. Solar batteries, which operate on the principle that light falling on photosensitive substances (Photo Cells) causes a flow of electricity, play an important part in space satellites and, as they become more efficient, are finding increasing use on the earth.
Thermoelectric generators convert the heat generated by solar energy directly into electricity. Several projects have produced electricity on a large scale by using the solar energy available in desert areas. In one system, large numbers of solar batteries generate electricity for Coconut Island, off the coast of Australia. In another, oil flows through pipes that are set in reflecting parabolic troughs that can trap the heat from sunlight falling on them. The heat from the oil is then converted into electricity. Heat from the sun is used in air-drying a variety of materials and in producing salt by the evaporation of seawater. Solar heating systems can supply heat and hot water for domestic use; heat collected in special plates on the roof of a house is stored in rocks or water held in a large container. Such systems, however, usually require a conventional heater to supplement them. Solar stoves, which focus the sun's heat directly, are employed in regions where there is much perennial sunlight.

Earth At Aphelion (1.017 AU From Sun)
This weekend, on July 6th, our planet will reach the distant end -- a point astronomers call aphelion. We'll be farther from the Sun than we are at any other time of the year.
All planets in our solar system travel around the Sun in elliptical orbits. It's Kepler's 1st Law, says University of Florida astronomy professor George Lebo. The eccentricity of Earth's orbit is 1.7%. In January when we're closest to the Sun (perihelion), the distance is 147.5 million km. This weekend we will be 152.6 million km away--a five million kilometer difference.
A distant sun means less sunlight for our planet. Averaged over the globe, sunlight falling on Earth at aphelion is about 7% less intense than it is at perihelion, says Roy Spencer of NASA's Global Hydrology and Climate Center (GHCC).

I missed Aphelion day but celebrated it by finding some splendid geodes in a dry creek bed. Ia m getting better and better at this finding things on the f\ground. My host is even better at it since he is an archaeologist and trained for such things. What he misses I find and vice versa.
In Hawaii, we get air pollution from China! No place on earth is separate and immune to the presence of bad things. Only in ancient times, perhaps. The world has gotten much smaller in recent decades.

LAHINA NOON
In the tropics, there are two days each year when the sun is exactly overhead at local noon. This event only happens in the tropics; the sun is never overhead in the temperate or arctic zones of the world.
Since there was not a convenient single term for “that day when the sun is exactly overhead at local noon,” the Bishop Museum planetarium sponsored a contest ten years ago to select a name for this event. “Lahaina Noon” was the winner. “Lahaina” means “cruel sun” in Hawaiian. One does not need to be in the town of Lahaina, Maui, to see this event….anywhere in the tropics will do.
Lahaina noon occurs only once on the tropic of Cancer, 23.5 degrees north of the equator, on the first day of summer. It occurs only once on the tropic of Capricorn, 23.5 degrees south of the equator, on the first day of winter. For all other locations in the tropics, this event occurs twice a year.
The closer a given latitude is to the tropic of Cancer, the closer the Lahaina noon dates will be to June 21. For instance, Lahaina noon dates in Lihue, Kaua‘i, occur on May 31 and July 11. This is 21 days before and 21 days after the first day of summer on June 21. Lahaina noon dates in Hilo, Hawai‘i, much further south, occur on May 18 and July 24. This is 34 days before, and 33 days after, the June solstice.

SOLAR ACTIVITY ALERT:
Sunspot 39 is remarkably active. In recent days it has unleashed two X-class solar flares, caused radio blackouts on Earth, and fueled an ongoing radiation storm. High solar activity will likely continue for the rest of the week at least.
Two big spots appear on the Sun today: sunspot 39 (left) and 36 (right). Both pose a threat for powerful flares. You can see these active regions yourself, but never look directly at the Sun! Use safe solar projection techniques.

SAFE SUN WATCHING
Never view the Sun directly with the naked eye or with any unfiltered optical device, such as binoculars or a telescope!
If you're thinking of viewing the Sun, your first concern should always be eye safety. Serious eye damage can result from even a brief glimpse of our star -- Galileo looked at the Sun through a telescope 400 years ago and suffered permanent eye damage. If it happened to Galileo, it can happen to you!
One safe way to observe sunspots or eclipses is to project an image of the Sun through a telescope or binoculars onto a white screen -- paper plates, walls and sidewalks all work nicely. If you're using a telescope, be sure that any small finder telescope is capped. If you're using binoculars, keep the cover on one of the two tubes. Never look through a telescope or binoculars to point them at the Sun -- partial or total blindness will almost surely result.
On the screen you should see a bright circle of light. This is the disc of the Sun. Adjust the distance between the screen and the telescope until the disk is about the size of a small paper plate. The image will probably be blurred; focus your telescope until the circle becomes sharp. Using this method you can see considerable detail in and around sunspot groups.
Pinhole projectors and certain types of solar filters can also afford a safe view of the Sun. Pinhole projectors usually produce a small and unsatisfying image, but they are better than nothing if you don't have a telescope or binoculars.

Thank you, John! Just like Vampires, we do not cast shadows in Hawaii on July 24th... but that is only at noon. Shortly thereafter, we begin to cast a shadow again just like every other mortal.

To be in this count the volcano had to be erupting ash or in active lava flow. Not all listed volcanoes met this criterion and were excluded. Late reporting of volcanic activity did not exclude a volcano, as happened with Indonesia, but the report was included the date it was received. Many volcanoes appear in several issues
The FIVE Rule of the Earth and Sun Digest:
FIVE quakes of 5.x magnitude in FIVE Days
can cause a volcano to erupt ash and gas FIVE miles
to the jet streams, where it can circle the globe in FIVE days.
